BLINDING LIGHT RAYS FROM A ZEPPELIN.
FRENCH INVENTION USED BY
General Gallieni (French Minister for War) has ordered experiments to be made with the Dussaud cold ray? with a view to their employment against Zeppelins. M. Dussaud's invention was mentioned at the Academy of Science four years ago. Briefly it means tbe utilising in an electric lamp of almost the entire current as light, instead of allowing 80 per cent to 90 per cent to be lost as heat. Shortly after the war broke out M Dusaand offored his servico to the Ministry of War, but in spite of the instructions of tbe then Minister, M. Millerand, red tapa blocked the way. M Dussaud
was referred from bureau to bureau until after four months' vain effort to obtain a hearing be abandoned the task in despair.
A year before the war—in 1918 — the German rights had been purchased by a Berlin firm. It i 3 a curious fact tbat on July 17, 1914, a fortnight be
fore war was declared, the German Ambassador in Paris called on M
to inquiie whether the latter bad effected any improvements in his x apparatus. Four days later the Aus tnan Ambassador followed suit. Now the French aviators who pursued the Zpppeiin^which raided Paris at the end of lost month deolare thai. they were literally blinded by the stream of light from tbe Zeppelin.
"At certain moments," says one of tbe watchers, "an extraordinarily in
tenae ray of light proceeded from the Zepplin, so tbat the street was lighted as though by the sun."
It is supposed that the German military authorities have already ap plied the Dussaud invention to their J aircraft. Be this as it may, General Gallieni ba=r now ordered experiments to be made with this light with a view to proving whether it is capable as a searchlight of piercing the clouds and banks of mist behind which the Zeppelin love 3to hide—-"Daily Newe."
